- Celtics forward Grant Williams is headed to restricted free agency but his mind is focused on the postseason, he told Sam Yip of HoopsHype in a wide-ranging interview. “For me, it’s always been about playing to the best ability that I can, and winning as many titles as I can while I’m here. So after that, whatever happens this free agency cycle, that’ll be determined this summer after hopefully, we got the ring in my hand,” Williams said. “So that’s the main priority. No. 1 is focused on getting this ring first.”
